The top and bottom rails, as shown in Fig. 2, may be grooved for the insertion of the two-section rubber strips l9 and 20, while the side rails may be equipped or provided with one bifurcated section of the bar I! (or l6), as shown by the dotted lines 1-1: in Fig. 3. Or the rail itself may be similarly grooved to insure the same result.

Notwithstanding the patents to which I have referred, and possibly others, the type of sashbar now more generallyin use is adapted for the mounting of panes of glass set in putty and stabilized by glazing nails or brads driven into the wood of the frame. It has been found that under continuous exposure to weather and climatic conditions the nails rust and are easily dislodged, and sooner or later the putty hardens and becomes brittle and cracks and crumbles, with result that the panes slip or blow out when the wind gets above a normal velocity. This means the dripping of water into the interior of the windowed structure and the escape of a great quantity of heat in cool weather-matters of much importance in greenhouse construction.

I claim as my invention- 1. A multiple-pane window-sash comprising the usual sash-rails and transversely-disposed sash-bars, all provided with means for receiving and resiliently retaining under compressive forces individual glass panes arranged in vertical rows, the panes in each row having restricted relative movement with reference to each other and with contigous edges overlapping and in direct contact with each other, said means including supplemental means for augmenting the compressive forces acting upon the overlapping edges.

2. In a'muitiple-pane window-sash comprising the usual sash-rails and transversely disposed sash-bars, self-retained strips of pliant and resilient material peripherally arranged in said rails and bars, said strips comprising at least two layers of material which combine to provide a stepped groove to yieldingly receive and retain the glass panes individually.

3. In a multiple-pane window-sash comprising the usual sash-rails and transversely disposed sash-bars, self-retained strips of pliant and resilient material peripherally arranged in said rails and bars, said strips comprising at least two layers of material which combine to provide a stepped groove to yieldingly receive and retain rated rows.

4. In a multiple-pane window-sash comprising the usual sash-rails and transversely disposed sash-bars, self-retained strips of pliant and resilient material peripherally arranged in said rails and bars, said strips comprising at least two layers of material which combine to provide a stepped groove to yieldingly receive and retain the glass panes individually in resiliently separated rows, contiguous end edges of the panes of each row being in directly contacting and overlapping relationship.

5. In a multiple-pane window-sash comprising the usual sash-rails and transversely disposed sash-bars, strips of pliant and resilient material peripherally arranged in said rails and bars, said strips comprising at least two layers of material which combine to provide a stepped groove to yieldingly receive and retain the glass panes individually in resiliently separated rows, contiguous end edges of the panes of each row being in directly contacting and overlapping relationship, and means supplemental to said pliant and resilient strips for augmenting the normal compressive seating forces thereof.

6. In a multiple-pane window-sash comprising the usual sash-rails and transversely disposed sash-bars, strips of pliant and resilient material peripherally arranged in said rails and bars, said strips comprising at least two layers of material which combine to provide a stepped grooIe to yieldingly receive and retain the glass panes individually in resiliently separated rows, contiguous end edges of the panes of each row being in directly contacting and overlapping relationship and abutting suitable shoulders provided and suitably spaced in said sash rails to augment the normal compressive seating forces of said strips.

7. In a multiple-pane window sash comprising the usual sash-rails and transversely disposed sash-bars, strips of plant and resilient material peripherally arranged and self-retained in said rails and bars, said strips comprising at least two layers of material which combine to provide a stepped groove to yieldingly receive and retain the glass panes individually in resiliently separated rows, contiguous end edges of the panes of each row being in directly contacting and overlapping relationship, abutting suitable shoulders provided and suitably spaced in said pliant and resilient strips, at least one of said sash-bars being provided with nubs to supplement the normal compressive seating forces of said strips.
